drilling/tapping 25d heads for turbo

Post by xbmxxx »

I once found a thread (I think it was on here) with pictures and a step by step on drilling/tapping the 25d heads for turbo oil/coolant, and now I cant find it. Any ideas?

Try this. Also most shops can drill and tap a spot on the head for oil.
